The SHIMANO ULTEGRA R8100 series "FC-R8100-P" is a dual-sided power meter integrated crankset that supports independent left and right measurement.
Shimano's unique strain gauge technology achieves highly accurate power measurement of ±2% across the entire calibration range. It supports not only left and right power balance but also force vector measurement, which helps in analyzing pedaling efficiency and optimizing training.
The power meter is smartly integrated into the crank, ensuring waterproofing and high durability. The active temperature compensation function makes it less susceptible to environmental changes, enabling stable measurement regardless of season or conditions.
Furthermore, it supports Bluetooth® LE and ANT+, allowing easy connection to cycling computers and training apps. This high-performance power meter crank is widely used by race-oriented riders, long-distance riders, and training enthusiasts alike.

The crank-integrated design gives it a clean look, and it also seems to have excellent waterproofing and durability. It's recommended not only for riders aiming for races but also for long-distance riders who want to get faster efficiently.
As expected from the ULTEGRA grade, I believe it is a power meter crank with an excellent balance of performance and price.
